BorderStyle Enumeration

Specifies the border style for a control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

'Declaration
<ComVisibleAttribute(True)> _
Public Enumeration BorderStyle
'Usage
Dim instance As BorderStyle

/** @attribute ComVisibleAttribute(true) */ 
public enum BorderStyle
ComVisibleAttribute(true) 
public enum BorderStyle

 Member nameDescription
Supported by the .NET Compact FrameworkFixed3DA three-dimensional border. 
Supported by the .NET Compact FrameworkFixedSingleA single-line border. 
Supported by the .NET Compact FrameworkNoneNo border. 

Use the members of this enumeration to set the border style for controls that have a changeable border.

The following code example demonstrates how to use the BorderStyle enumeration and the TreeView.BorderStyle, TreeView.HideSelection and the TreeView.ShowRootLines properties. To run this example, paste the following code in a form and call the InitializeTreeView method in the form's constructor or Load method.


' Declare the TreeView control.
Friend WithEvents TreeView1 As System.Windows.Forms.TreeView

' Initialize the TreeView to blend with the form, giving it the 
' same color as the form and no border.
Private Sub InitializeTreeView()

    ' Create a new TreeView control and set the location and size.
    Me.TreeView1 = New System.Windows.Forms.TreeView
    Me.TreeView1.Location = New System.Drawing.Point(72, 48)
    Me.TreeView1.Size = New System.Drawing.Size(200, 200)

    ' Set the BorderStyle property to none, the BackColor property to  
    ' the form's backcolor, and the Scrollable property to false.  
    ' This allows the TreeView to blend in form.
    Me.TreeView1.BorderStyle = BorderStyle.None
    Me.TreeView1.BackColor = Me.BackColor
    Me.TreeView1.Scrollable = False

    
    ' Set the ShowRootLines and ShowLines properties to false to 
    ' give the TreeView a list-like appearance.
    Me.TreeView1.ShowRootLines = False
    Me.TreeView1.ShowLines = False

    ' Add the nodes.
    Me.TreeView1.Nodes.AddRange(New System.Windows.Forms.TreeNode() _
        {New System.Windows.Forms.TreeNode("Features", _
        New System.Windows.Forms.TreeNode() _
        {New System.Windows.Forms.TreeNode("Full Color"), _

        New System.Windows.Forms.TreeNode("Windows 98 or later"), _
        New System.Windows.Forms.TreeNode("100 MB Disk space")})})

    ' Set the tab index and add the TreeView to the form.
    Me.TreeView1.TabIndex = 0
    Me.Controls.Add(Me.TreeView1)
